The perfect little book about colours for fans of The Dinosaur That Pooped series. When Dino and Danny see a rainbow in the sky, they go through and name all the colours they can see. But soon they notice there is one important colour missing and Dinosaur is keen to help correct it. A very funny short Dino story in board book format. "A work of genius." (The Bookseller on The Dinosaur That Pooped Christmas).
